Given

The speed of light through a medium is


v=1.24*10^8\text{ m/s}

To find

The type of material

Step-by-step explanation

The velocity through a medium is given by


v=(c)/(n)

where c is the speed of light in .

n is the refractive index of the material

Thus,


\begin{gathered} 1.24*10^8=(3*10^8)/(n) \\ \Rightarrow n=2..419 \end{gathered}

Thus the refractive index is 2.419

We know diamond has a refractive index of 2.417-2.419

Conclusion

The material is diamond
